PERLDIAG(1) Perl Programmers Reference Guide PERLDIAG(1)
NAME
perldiag - various Perl diagnostics
DESCRIPTION
These messages are classified as follows (listed in increasing order of
desperation):
(W) A warning (optional).
(D) A deprecation (optional).
(S) A severe warning (default).
(F) A fatal error (trappable).
(P) An internal error you should never see (trappable).
(X) A very fatal error (nontrappable).
(A) An alien error message (not generated by Perl).
The majority of messages from the first three classifications above (W,
D & S) can be controlled using the "warnings" pragma.
If a message can be controlled by the "warnings" pragma, its warning
category is included with the classification letter in the description
below.
Optional warnings are enabled by using the "warnings" pragma or the -w
and -W switches. Warnings may be captured by setting $SIG{__WARN__} to
a reference to a routine that will be called on each warning instead of
printing it. See perlvar.
Default warnings are always enabled unless they are explicitly disabled
with the "warnings" pragma or the -X switch.
Trappable errors may be trapped using the eval operator. See "eval" in
perlfunc. In almost all cases, warnings may be selectively disabled or
promoted to fatal errors using the "warnings" pragma. See warnings.
The messages are in alphabetical order, without regard to upper or
lower-case. Some of these messages are generic. Spots that vary are
denoted with a %s or other printf-style escape. These escapes are
ignored by the alphabetical order, as are all characters other than
letters. To look up your message, just ignore anything that is not a
letter.
accept() on closed socket %s
(W closed) You tried to do an accept on a closed socket. Did you
forget to check the return value of your socket() call? See
"accept" in perlfunc.
Allocation too large: %lx
(X) You cant allocate more than 64K on an MS-DOS machine.
! allowed only after types %s
(F) The ! is allowed in pack() or unpack() only after certain
types. See "pack" in perlfunc.
Ambiguous call resolved as CORE::%s(), qualify as such or use &
(W ambiguous) A subroutine you have declared has the same name as a
Perl keyword, and you have used the name without qualification for
calling one or the other. Perl decided to call the builtin because
the subroutine is not imported.
To force interpretation as a subroutine call, either put an amper
sand before the subroutine name, or qualify the name with its pack
age. Alternatively, you can import the subroutine (or pretend that
its imported with the "use subs" pragma).
To silently interpret it as the Perl operator, use the "CORE::"
prefix on the operator (e.g. "CORE::log($x)") or declare the sub
routine to be an object method (see "Subroutine Attributes" in
perlsub or attributes).
Ambiguous range in transliteration operator
(F) You wrote something like "tr/a-z-0//" which doesnt mean any
thing at all. To include a "-" character in a transliteration, put
it either first or last. (In the past, "tr/a-z-0//" was synonymous
with "tr/a-y//", which was probably not what you would have
expected.)
Ambiguous use of %s resolved as %s
(W ambiguous)(S) You said something that may not be interpreted the
way you thought. Normally its pretty easy to disambiguate it by
supplying a missing quote, operator, parenthesis pair or declara
tion.
| and < may not both be specified on command line
(F) An error peculiar to VMS. Perl does its own command line redi
rection, and found that STDIN was a pipe, and that you also tried
to redirect STDIN using may not both be specified on command line
(F) An error peculiar to VMS. Perl does its own command line redi
rection, and thinks you tried to redirect stdout both to a file and
into a pipe to another command. You need to choose one or the
other, though nothings stopping you from piping into a program or
Perl script which splits output into two streams, such as
open(OUT,">$ARGV[0]") or die "Cant write to $ARGV[0]: $!";
while () {
print;
print OUT;
}
close OUT;
Applying %s to %s will act on scalar(%s)
(W misc) The pattern match ("//"), substitution ("s///"), and
transliteration ("tr///") operators work on scalar values. If you
apply one of them to an array or a hash, it will convert the array
or hash to a scalar value -- the length of an array, or the popula
tion info of a hash -- and then work on that scalar value. This is
probably not what you meant to do. See "grep" in perlfunc and
"map" in perlfunc for alternatives.
Args must match #! line
(F) The setuid emulator requires that the arguments Perl was
invoked with match the arguments specified on the #! line. Since
some systems impose a one-argument limit on the #! line, try com
bining switches; for example, turn "-w -U" into "-wU".
Arg too short for msgsnd
(F) msgsnd() requires a string at least as long as sizeof(long).
%s argument is not a HASH or ARRAY element
(F) The argument to exists() must be a hash or array element, such
as:
$foo{$bar}
$ref->{"susie"}[12]
%s argument is not a HASH or ARRAY element or slice
(F) The argument to delete() must be either a hash or array ele
ment, such as:
$foo{$bar}
$ref->{"susie"}[12]
or a hash or array slice, such as:
@foo[$bar, $baz, $xyzzy]
@{$ref->[12]}{"susie", "queue"}
%s argument is not a subroutine name
(F) The argument to exists() for "exists &sub" must be a subroutine
name, and not a subroutine call. "exists &sub()" will generate
this error.
Argument "%s" isnt numeric%s
(W numeric) The indicated string was fed as an argument to an oper
ator that expected a numeric value instead. If youre fortunate
the message will identify which operator was so unfortunate.
Argument list not closed for PerlIO layer "%s"
(W layer) When pushing a layer with arguments onto the Perl I/O
system you forgot the ) that closes the argument list. (Layers
take care of transforming data between external and internal repre
sentations.) Perl stopped parsing the layer list at this point and
did not attempt to push this layer. If your program didnt explic
itly request the failing operation, it may be the result of the
value of the environment variable PERLIO.
Array @%s missing the @ in argument %d of %s()
(D deprecated) Really old Perl let you omit the @ on array names in
some spots. This is now heavily deprecated.
assertion botched: %s
(P) The malloc package that comes with Perl had an internal fail
ure.
Assertion failed: file "%s"
(P) A general assertion failed. The file in question must be exam
ined.
Assignment to both a list and a scalar
(F) If you assign to a conditional operator, the 2nd and 3rd argu
ments must either both be scalars or both be lists. Otherwise Perl
wont know which context to supply to the right side.
A thread exited while %d threads were running
(W threads)(S) When using threaded Perl, a thread (not necessarily
the main thread) exited while there were still other threads run
ning. Usually its a good idea to first collect the return values
of the created threads by joining them, and only then exit from the
main thread. See threads.
Attempt to access disallowed key %s in a restricted hash
(F) The failing code has attempted to get or set a key which is not
in the current set of allowed keys of a restricted hash.
Attempt to bless into a reference
(F) The CLASSNAME argument to the bless() operator is expected to
be the name of the package to bless the resulting object into.
Youve supplied instead a reference to something: perhaps you wrote
bless $self, $proto;
when you intended
bless $self, ref($proto) || $proto;
If you actually want to bless into the stringified version of the
reference supplied, you need to stringify it yourself, for example
by:
bless $self, "$proto";
Attempt to delete disallowed key %s from a restricted hash
(F) The failing code attempted to delete from a restricted hash a
key which is not in its key set.
Attempt to delete readonly key %s from a restricted hash
(F) The failing code attempted to delete a key whose value has been
declared readonly from a restricted hash.
Attempt to free non-arena SV: 0x%lx
(P internal) All SV objects are supposed to be allocated from are
nas that will be garbage collected on exit. An SV was discovered
to be outside any of those arenas.
Attempt to free nonexistent shared string
(P internal) Perl maintains a reference counted internal table of
strings to optimize the storage and access of hash keys and other
strings. This indicates someone tried to decrement the reference
count of a string that can no longer be found in the table.
Attempt to free temp prematurely
(W debugging) Mortalized values are supposed to be freed by the
free_tmps() routine. This indicates that something else is freeing
the SV before the free_tmps() routine gets a chance, which means
that the free_tmps() routine will be freeing an unreferenced scalar
when it does try to free it.
Attempt to free unreferenced glob pointers
(P internal) The reference counts got screwed up on symbol aliases.
Attempt to free unreferenced scalar
(W internal) Perl went to decrement the reference count of a scalar
to see if it would go to 0, and discovered that it had already gone
to 0 earlier, and should have been freed, and in fact, probably was
freed. This could indicate that SvREFCNT_dec() was called too many
times, or that SvREFCNT_inc() was called too few times, or that the
SV was mortalized when it shouldnt have been, or that memory has
been corrupted.
Attempt to join self
(F) You tried to join a thread from within itself, which is an
impossible task. You may be joining the wrong thread, or you may
need to move the join() to some other thread.
Attempt to pack pointer to temporary value
(W pack) You tried to pass a temporary value (like the result of a
function, or a computed expression) to the "p" pack() template.
This means the result contains a pointer to a location that could
become invalid anytime, even before the end of the current state
ment. Use literals or global values as arguments to the "p" pack()
template to avoid this warning.
Attempt to set length of freed array
(W) You tried to set the length of an array which has been freed.
You can do this by storing a reference to the scalar representing
the last index of an array and later assigning through that refer
ence. For example
$r = do {my @a; \$#a};
$$r = 503
Attempt to use reference as lvalue in substr
(W substr) You supplied a reference as the first argument to sub
str() used as an lvalue, which is pretty strange. Perhaps you
forgot to dereference it first. See "substr" in perlfunc.
Bad arg length for %s, is %d, should be %s
(F) You passed a buffer of the wrong size to one of msgctl(), sem
ctl() or shmctl(). In C parlance, the correct sizes are, respec
tively, sizeof(struct msqid_ds *), sizeof(struct semid_ds *), and
sizeof(struct shmid_ds *).
Bad evalled substitution pattern
(F) Youve used the "/e" switch to evaluate the replacement for a
substitution, but perl found a syntax error in the code to evalu
ate, most likely an unexpected right brace }.
Bad filehandle: %s
(F) A symbol was passed to something wanting a filehandle, but the
symbol has no filehandle associated with it. Perhaps you didnt do
an open(), or did it in another package.
Bad free() ignored
(S malloc) An internal routine called free() on something that had
never been malloc()ed in the first place. Mandatory, but can be
disabled by setting environment variable "PERL_BADFREE" to 0.
This message can be seen quite often with DB_File on systems with
"hard" dynamic linking, like "AIX" and "OS/2". It is a bug of
"Berkeley DB" which is left unnoticed if "DB" uses forgiving system
malloc().
Bad hash
(P) One of the internal hash routines was passed a null HV pointer.
Bad index while coercing array into hash
(F) The index looked up in the hash found as the 0th element of a
pseudo-hash is not legal. Index values must be at 1 or greater.
See perlref.
Badly placed ()s
(A) Youve accidentally run your script through csh instead of
Perl. Check the #! line, or manually feed your script into Perl
yourself.
Bad name after %s::
(F) You started to name a symbol by using a package prefix, and
then didnt finish the symbol. In particular, you cant interpo
late outside of quotes, so
$var = myvar;
$sym = mypack::$var;
is not the same as
$var = myvar;
$sym = "mypack::$var";
Bad realloc() ignored
(S malloc) An internal routine called realloc() on something that
had never been malloc()ed in the first place. Mandatory, but can be
disabled by setting environment variable "PERL_BADFREE" to 1.
Bad symbol for array
(P) An internal request asked to add an array entry to something
that wasnt a symbol table entry.
Bad symbol for filehandle
(P) An internal request asked to add a filehandle entry to some
thing that wasnt a symbol table entry.
Bad symbol for hash
(P) An internal request asked to add a hash entry to something that
wasnt a symbol table entry.
Bareword found in conditional
(W bareword) The compiler found a bareword where it expected a con
ditional, which often indicates that an || or && was parsed as part
of the last argument of the previous construct, for example:
open FOO || die;
It may also indicate a misspelled constant that has been inter
preted as a bareword:
use constant TYPO => 1;
if (TYOP) { print "foo" }
The "strict" pragma is useful in avoiding such errors.
Bareword "%s" not allowed while "strict subs" in use
(F) With "strict subs" in use, a bareword is only allowed as a sub
routine identifier, in curly brackets or to the left of the "=>"
symbol. Perhaps you need to predeclare a subroutine?
Bareword "%s" refers to nonexistent package
(W bareword) You used a qualified bareword of the form "Foo::", but
the compiler saw no other uses of that namespace before that point.
Perhaps you need to predeclare a package?
BEGIN failed--compilation aborted
(F) An untrapped exception was raised while executing a BEGIN sub
routine. Compilation stops immediately and the interpreter is
exited.
BEGIN not safe after errors--compilation aborted
(F) Perl found a "BEGIN {}" subroutine (or a "use" directive, which
implies a "BEGIN {}") after one or more compilation errors had
already occurred. Since the intended environment for the "BEGIN
{}" could not be guaranteed (due to the errors), and since subse
quent code likely depends on its correct operation, Perl just gave
up.
\1 better written as $1
(W syntax) Outside of patterns, backreferences live on as vari
ables. The use of backslashes is grandfathered on the right-hand
side of a substitution, but stylistically its better to use the
variable form because other Perl programmers will expect it, and it
works better if there are more than 9 backreferences.
Binary number > 0b11111111111111111111111111111111 non-portable
(W portable) The binary number you specified is larger than 2**32-1
(4294967295) and therefore non-portable between systems. See perl
port for more on portability concerns.
bind() on closed socket %s
(W closed) You tried to do a bind on a closed socket. Did you for
get to check the return value of your socket() call? See "bind" in
perlfunc.
binmode() on closed filehandle %s
(W unopened) You tried binmode() on a filehandle that was never
opened. Check you control flow and number of arguments.
Bit vector size > 32 non-portable
(W portable) Using bit vector sizes larger than 32 is non-portable.
Bizarre copy of %s in %s
(P) Perl detected an attempt to copy an internal value that is not
copyable.
Buffer overflow in prime_env_iter: %s
(W internal) A warning peculiar to VMS. While Perl was preparing
to iterate over %ENV, it encountered a logical name or symbol
definition which was too long, so it was truncated to the string
shown.
Callback called exit
(F) A subroutine invoked from an external package via call_sv()
exited by calling exit.
%s() called too early to check prototype
(W prototype) Youve called a function that has a prototype before
the parser saw a definition or declaration for it, and Perl could
not check that the call conforms to the prototype. You need to
either add an early prototype declaration for the subroutine in
question, or move the subroutine definition ahead of the call to
get proper prototype checking. Alternatively, if you are certain
that youre calling the function correctly, you may put an amper
sand before the name to avoid the warning. See perlsub.
Cannot compress integer in pack
(F) An argument to pack("w",...) was too large to compress. The
BER compressed integer format can only be used with positive inte
gers, and you attempted to compress Infinity or a very large number
(> 1e308). See "pack" in perlfunc.
Cannot compress negative numbers in pack
(F) An argument to pack("w",...) was negative. The BER compressed
integer format can only be used with positive integers. See "pack"
in perlfunc.
Can only compress unsigned integers in pack
(F) An argument to pack("w",...) was not an integer. The BER com
pressed integer format can only be used with positive integers, and
you attempted to compress something else. See "pack" in perlfunc.
Cant bless non-reference value
(F) Only hard references may be blessed. This is how Perl
"enforces" encapsulation of objects. See perlobj.
Cant call method "%s" in empty package "%s"
(F) You called a method correctly, and it correctly indicated a
package functioning as a class, but that package doesnt have ANY
THING defined in it, let alone methods. See perlobj.
Cant call method "%s" on an undefined value
(F) You used the syntax of a method call, but the slot filled by
the object reference or package name contains an undefined value.
Something like this will reproduce the error:
$BADREF = undef;
process $BADREF 1,2,3;
$BADREF->process(1,2,3);
Cant call method "%s" on unblessed reference
(F) A method call must know in what package its supposed to run.
It ordinarily finds this out from the object reference you supply,
but you didnt supply an object reference in this case. A refer
ence isnt an object reference until it has been blessed. See per
lobj.
Cant call method "%s" without a package or object reference
(F) You used the syntax of a method call, but the slot filled by
the object reference or package name contains an expression that
returns a defined value which is neither an object reference nor a
package name. Something like this will reproduce the error:
$BADREF = 42;
process $BADREF 1,2,3;
$BADREF->process(1,2,3);
Cant chdir to %s
(F) You called "perl -x/foo/bar", but "/foo/bar" is not a directory
that you can chdir to, possibly because it doesnt exist.
Cant check filesystem of script "%s" for nosuid
(P) For some reason you cant check the filesystem of the script
for nosuid.
Cant coerce array into hash
(F) You used an array where a hash was expected, but the array has
no information on how to map from keys to array indices. You can
do that only with arrays that have a hash reference at index 0.
Cant coerce %s to integer in %s
(F) Certain types of SVs, in particular real symbol table entries
(typeglobs), cant be forced to stop being what they are. So you
cant say things like:
*foo += 1;
You CAN say
$foo = *foo;
$foo += 1;
but then $foo no longer contains a glob.
Cant coerce %s to number in %s
(F) Certain types of SVs, in particular real symbol table entries
(typeglobs), cant be forced to stop being what they are.
Cant coerce %s to string in %s
(F) Certain types of SVs, in particular real symbol table entries
(typeglobs), cant be forced to stop being what they are.
Cant create pipe mailbox
(P) An error peculiar to VMS. The process is suffering from
exhausted quotas or other plumbing problems.
Cant declare class for non-scalar %s in "%s"
(F) Currently, only scalar variables can be declared with a spe
cific class qualifier in a "my" or "our" declaration. The seman
tics may be extended for other types of variables in future.
Cant declare %s in "%s"
(F) Only scalar, array, and hash variables may be declared as "my"
or "our" variables. They must have ordinary identifiers as names.
Cant do inplace edit: %s is not a regular file
(S inplace) You tried to use the -i switch on a special file, such
as a file in /dev, or a FIFO. The file was ignored.
Cant do inplace edit on %s: %s
(S inplace) The creation of the new file failed for the indicated
reason.
Cant do inplace edit without backup
(F) Youre on a system such as MS-DOS that gets confused if you try
reading from a deleted (but still opened) file. You have to say
"-i.bak", or some such.
Cant do inplace edit: %s would not be unique
(S inplace) Your filesystem does not support filenames longer than
14 characters and Perl was unable to create a unique filename dur
ing inplace editing with the -i switch. The file was ignored.
Cant do {n,m} with n > m in regex; marked by {key}", where $ar is a
reference to a pseudo-hash. That hasnt been implemented yet, but
you can get a similar effect by localizing the corresponding array
element directly -- "local $ar->[$ar->[0]{key}]".
Cant localize through a reference
(F) You said something like "local $$ref", which Perl cant cur
rently handle, because when it goes to restore the old value of
whatever $ref pointed to after the scope of the local() is fin
ished, it cant be sure that $ref will still be a reference.
Cant locate %s
(F) You said to "do" (or "require", or "use") a file that couldnt
be found. Perl looks for the file in all the locations mentioned in
@INC, unless the file name included the full path to the file.
Perhaps you need to set the PERL5LIB or PERL5OPT environment vari
able to say where the extra library is, or maybe the script needs
to add the library name to @INC. Or maybe you just misspelled the
name of the file. See "require" in perlfunc and lib.
Cant locate auto/%s.al in @INC
(F) A function (or method) was called in a package which allows
autoload, but there is no function to autoload. Most probable
causes are a misprint in a function/method name or a failure to
"AutoSplit" the file, say, by doing "make install".
Cant locate loadable object for module %s in @INC
(F) The module you loaded is trying to load an external library,
like for example, "foo.so" or "bar.dll", but the DynaLoader module
was unable to locate this library. See DynaLoader.
Cant locate object method "%s" via package "%s"
(F) You called a method correctly, and it correctly indicated a
package functioning as a class, but that package doesnt define
that particular method, nor does any of its base classes. See per
lobj.
Cant locate package %s for @%s::ISA
(W syntax) The @ISA array contained the name of another package
that doesnt seem to exist.
Cant locate PerlIO%s
(F) You tried to use in open() a PerlIO layer that does not exist,
e.g. open(FH, ">:nosuchlayer", "somefile").
Cant make list assignment to \%ENV on this system
(F) List assignment to %ENV is not supported on some systems,
notably VMS.
Cant modify %s in %s
(F) You arent allowed to assign to the item indicated, or other
wise try to change it, such as with an auto-increment.
Cant modify nonexistent substring
(P) The internal routine that does assignment to a substr() was
handed a NULL.
Cant modify non-lvalue subroutine call
(F) Subroutines meant to be used in lvalue context should be
declared as such, see "Lvalue subroutines" in perlsub.
Cant msgrcv to read-only var
(F) The target of a msgrcv must be modifiable to be used as a
receive buffer.
Cant "next" outside a loop block
(F) A "next" statement was executed to reiterate the current block,
but there isnt a current block. Note that an "if" or "else" block
doesnt count as a "loopish" block, as doesnt a block given to
sort(), map() or grep(). You can usually double the curlies to get
the same effect though, because the inner curlies will be consid
ered a block that loops once. See "next" in perlfunc.
Cant open %s: %s
(S inplace) The implicit opening of a file through use of the "<>"
filehandle, either implicitly under the "-n" or "-p" command-line
switches, or explicitly, failed for the indicated reason. Usually
this is because you dont have read permission for a file which you
named on the command line.
Cant open a reference
(W io) You tried to open a scalar reference for reading or writing,
using the 3-arg open() syntax :
open FH, >, $ref;
but your version of perl is compiled without perlio, and this form
of open is not supported.
Cant open bidirectional pipe
(W pipe) You tried to say "open(CMD, "|cmd|")", which is not sup
ported. You can try any of several modules in the Perl library to
do this, such as IPC::Open2. Alternately, direct the pipes output
to a file using ">", and then read it in under a different file
handle.
Cant open error file %s as stderr
(F) An error peculiar to VMS. Perl does its own command line redi
rection, and couldnt open the file specified after 2> or 2>>
on the command line for writing.
Cant open input file %s as stdin
(F) An error peculiar to VMS. Perl does its own command line redi
rection, and couldnt open the file specified after < on the com
mand line for reading.
Cant open output file %s as stdout
(F) An error peculiar to VMS. Perl does its own command line redi
rection, and couldnt open the file specified after > or >> on
the command line for writing.
Cant open output pipe (name: %s)
(P) An error peculiar to VMS. Perl does its own command line redi
rection, and couldnt open the pipe into which to send data des
tined for stdout.
Cant open perl script%s
(F) The script you specified cant be opened for the indicated rea
son.
If youre debugging a script that uses #!, and normally relies on
the shells $PATH search, the -S option causes perl to do that
search, so you dont have to type the path or which $scriptname.
Cant read CRTL environ
(S) A warning peculiar to VMS. Perl tried to read an element of
%ENV from the CRTLs internal environment array and discovered the
array was missing. You need to figure out where your CRTL mis
placed its environ or define PERL_ENV_TABLES (see perlvms) so that
environ is not searched.
Cant redefine active sort subroutine %s
(F) Perl optimizes the internal handling of sort subroutines and
keeps pointers into them. You tried to redefine one such sort sub
routine when it was currently active, which is not allowed. If you
really want to do this, you should write "sort { &func } @x"
instead of "sort func @x".
Cant "redo" outside a loop block
(F) A "redo" statement was executed to restart the current block,
but there isnt a current block. Note that an "if" or "else" block
doesnt count as a "loopish" block, as doesnt a block given to
sort(), map() or grep(). You can usually double the curlies to get
the same effect though, because the inner curlies will be consid
ered a block that loops once. See "redo" in perlfunc.
Cant remove %s: %s, skipping file
(S inplace) You requested an inplace edit without creating a backup
file. Perl was unable to remove the original file to replace it
with the modified file. The file was left unmodified.
Cant rename %s to %s: %s, skipping file
(S inplace) The rename done by the -i switch failed for some rea
son, probably because you dont have write permission to the direc
tory.
Cant reopen input pipe (name: %s) in binary mode
(P) An error peculiar to VMS. Perl thought stdin was a pipe, and
tried to reopen it to accept binary data. Alas, it failed.
Cant resolve method %s overloading %s in package %s
(F|P) Error resolving overloading specified by a method name (as
opposed to a subroutine reference): no such method callable via the
package. If method name is "???", this is an internal error.
Cant reswap uid and euid
(P) The setreuid() call failed for some reason in the setuid emula
tor of suidperl.
Cant return %s from lvalue subroutine
(F) Perl detected an attempt to return illegal lvalues (such as
temporary or readonly values) from a subroutine used as an lvalue.
This is not allowed.
Cant return outside a subroutine
(F) The return statement was executed in mainline code, that is,
where there was no subroutine call to return out of. See perlsub.
Cant return %s to lvalue scalar context
(F) You tried to return a complete array or hash from an lvalue
subroutine, but you called the subroutine in a way that made Perl
think you meant to return only one value. You probably meant to
write parentheses around the call to the subroutine, which tell
Perl that the call should be in list context.
Cant stat script "%s"
(P) For some reason you cant fstat() the script even though you
have it open already. Bizarre.
Cant swap uid and euid
(P) The setreuid() call failed for some reason in the setuid emula
tor of suidperl.
Cant take log of %g
(F) For ordinary real numbers, you cant take the logarithm of a
negative number or zero. Theres a Math::Complex package that comes
standard with Perl, though, if you really want to do that for the
negative numbers.
Cant take sqrt of %g
(F) For ordinary real numbers, you cant take the square root of a
negative number. Theres a Math::Complex package that comes stan
dard with Perl, though, if you really want to do that.
Cant undef active subroutine
(F) You cant undefine a routine thats currently running. You
can, however, redefine it while its running, and you can even
undef the redefined subroutine while the old routine is running.
Go figure.
Cant unshift
(F) You tried to unshift an "unreal" array that cant be unshifted,
such as the main Perl stack.
Cant upgrade that kind of scalar
(P) The internal sv_upgrade routine adds "members" to an SV, making
it into a more specialized kind of SV. The top several SV types
are so specialized, however, that they cannot be interconverted.
This message indicates that such a conversion was attempted.
Cant upgrade to undef
(P) The undefined SV is the bottom of the totem pole, in the scheme
of upgradability. Upgrading to undef indicates an error in the
code calling sv_upgrade.
Cant use anonymous symbol table for method lookup
(F) The internal routine that does method lookup was handed a sym
bol table that doesnt have a name. Symbol tables can become
anonymous for example by undefining stashes: "undef %Some::Pack
age::".
Cant use an undefined value as %s reference
(F) A value used as either a hard reference or a symbolic reference
must be a defined value. This helps to delurk some insidious
errors.
Cant use bareword ("%s") as %s ref while "strict refs" in use
(F) Only hard references are allowed by "strict refs". Symbolic
references are disallowed. See perlref.
Cant use %! because Errno.pm is not available
(F) The first time the %! hash is used, perl automatically loads
the Errno.pm module. The Errno module is expected to tie the %!
hash to provide symbolic names for $! errno values.
Cant use %s for loop variable
(F) Only a simple scalar variable may be used as a loop variable on
a foreach.
Cant use global %s in "my"
(F) You tried to declare a magical variable as a lexical variable.
This is not allowed, because the magic can be tied to only one
location (namely the global variable) and it would be incredibly
confusing to have variables in your program that looked like magi
cal variables but werent.
Cant use "my %s" in sort comparison
(F) The global variables $a and $b are reserved for sort compar
isons. You mentioned $a or $b in the same line as the <=> or cmp
operator, and the variable had earlier been declared as a lexical
variable. Either qualify the sort variable with the package name,
or rename the lexical variable.
Cant use %s ref as %s ref
(F) Youve mixed up your reference types. You have to dereference
a reference of the type needed. You can use the ref() function to
test the type of the reference, if need be.
Cant use string ("%s") as %s ref while "strict refs" in use
(F) Only hard references are allowed by "strict refs". Symbolic
references are disallowed. See perlref.
Cant use subscript on %s
(F) The compiler tried to interpret a bracketed expression as a
subscript. But to the left of the brackets was an expression that
didnt look like a hash or array reference, or anything else sub
scriptable.
Cant use \%c to mean $%c in expression
(W syntax) In an ordinary expression, backslash is a unary operator
that creates a reference to its argument. The use of backslash to
indicate a backreference to a matched substring is valid only as
part of a regular expression pattern. Trying to do this in ordi
nary Perl code produces a value that prints out looking like
SCALAR(0xdecaf). Use the $1 form instead.
Cant weaken a nonreference
(F) You attempted to weaken something that was not a reference.
Only references can be weakened.
Cant x= to read-only value
(F) You tried to repeat a constant value (often the undefined
value) with an assignment operator, which implies modifying the
value itself. Perhaps you need to copy the value to a temporary,
and repeat that.
Character in "C" format wrapped in pack
(W pack) You said
pack("C", $x)
where $x is either less than 0 or more than 255; the "C" format is
only for encoding native operating system characters (ASCII,
EBCDIC, and so on) and not for Unicode characters, so Perl behaved
as if you meant
pack("C", $x & 255)
If you actually want to pack Unicode codepoints, use the "U" format
instead.
Character in "c" format wrapped in pack
(W pack) You said
pack("c", $x)
where $x is either less than -128 or more than 127; the "c" format
is only for encoding native operating system characters (ASCII,
EBCDIC, and so on) and not for Unicode characters, so Perl behaved
as if you meant
pack("c", $x & 255);
If you actually want to pack Unicode codepoints, use the "U" format
instead.
close() on unopened filehandle %s
(W unopened) You tried to close a filehandle that was never opened.
Code missing after /
(F) You had a (sub-)template that ends with a /. There must be
another template code following the slash. See "pack" in perlfunc.
%s: Command not found
(A) Youve accidentally run your script through csh instead of
Perl. Check the #! line, or manually feed your script into Perl
yourself.
Compilation failed in require
(F) Perl could not compile a file specified in a "require" state
ment. Perl uses this generic message when none of the errors that
it encountered were severe enough to halt compilation immediately.
Complex regular subexpression recursion limit (%d) exceeded
(W regexp) The regular expression engine uses recursion in complex
situations where back-tracking is required. Recursion depth is
limited to 32766, or perhaps less in architectures where the stack
cannot grow arbitrarily. ("Simple" and "medium" situations are
handled without recursion and are not subject to a limit.) Try
shortening the string under examination; looping in Perl code (e.g.
with "while") rather than in the regular expression engine; or
rewriting the regular expression so that it is simpler or back
tracks less. (See perlfaq2 for information on Mastering Regular
Expressions.)
cond_broadcast() called on unlocked variable
(W threads) Within a thread-enabled program, you tried to call
cond_broadcast() on a variable which wasnt locked. The cond_broad
cast() function is used to wake up another thread that is waiting
in a cond_wait(). To ensure that the signal isnt sent before the
other thread has a chance to enter the wait, it is usual for the
signaling thread to first wait for a lock on variable. This lock
attempt will only succeed after the other thread has entered
cond_wait() and thus relinquished the lock.
cond_signal() called on unlocked variable
(W threads) Within a thread-enabled program, you tried to call
cond_signal() on a variable which wasnt locked. The cond_signal()
function is used to wake up another thread that is waiting in a
cond_wait(). To ensure that the signal isnt sent before the other
thread has a chance to enter the wait, it is usual for the signal
ing thread to first wait for a lock on variable. This lock attempt
will only succeed after the other thread has entered cond_wait()
and thus relinquished the lock.
connect() on closed socket %s
(W closed) You tried to do a connect on a closed socket. Did you
forget to check the return value of your socket() call? See "con
nect" in perlfunc.
Constant(%s)%s: %s
(F) The parser found inconsistencies either while attempting to
define an overloaded constant, or when trying to find the character
name specified in the "\N{...}" escape. Perhaps you forgot to load
the corresponding "overload" or "charnames" pragma? See charnames
and overload.
Constant is not %s reference
(F) A constant value (perhaps declared using the "use constant"
pragma) is being dereferenced, but it amounts to the wrong type of
reference. The message indicates the type of reference that was
expected. This usually indicates a syntax error in dereferencing
the constant value. See "Constant Functions" in perlsub and con
stant.
Constant subroutine %s redefined
(S) You redefined a subroutine which had previously been eligible
for inlining. See "Constant Functions" in perlsub for commentary
and workarounds.
Constant subroutine %s undefined
(W misc) You undefined a subroutine which had previously been eli
gible for inlining. See "Constant Functions" in perlsub for com
mentary and workarounds.
Copy method did not return a reference
(F) The method which overloads "=" is buggy. See "Copy Constructor"
in overload.
CORE::%s is not a keyword
(F) The CORE:: namespace is reserved for Perl keywords.
corrupted regexp pointers
(P) The regular expression engine got confused by what the regular
expression compiler gave it.
corrupted regexp program
(P) The regular expression engine got passed a regexp program with
out a valid magic number.
Corrupt malloc ptr 0x%lx at 0x%lx
(P) The malloc package that comes with Perl had an internal fail
ure.
Count after length/code in unpack
(F) You had an unpack template indicating a counted-length string,
but you have also specified an explicit size for the string. See
"pack" in perlfunc.
Deep recursion on subroutine "%s"
(W recursion) This subroutine has called itself (directly or indi
rectly) 100 times more than it has returned. This probably indi
cates an infinite recursion, unless youre writing strange bench
mark programs, in which case it indicates something else.
defined(@array) is deprecated
(D deprecated) defined() is not usually useful on arrays because it
checks for an undefined scalar value. If you want to see if the
array is empty, just use "if (@array) { # not empty }" for example.
defined(%hash) is deprecated
(D deprecated) defined() is not usually useful on hashes because it
checks for an undefined scalar value. If you want to see if the
hash is empty, just use "if (%hash) { # not empty }" for example.
%s defines neither package nor VERSION--version check failed
(F) You said something like "use Module 42" but in the Module file
there are neither package declarations nor a $VERSION.
Delimiter for here document is too long
(F) In a here document construct like "< operator
(F) The contents of a <> operator may not exceed the maximum size
of a Perl identifier. If youre just trying to glob a long list of
filenames, try using the glob() operator, or put the filenames into
a variable and glob that.
exec? Im not *that* kind of operating system
(F) The "exec" function is not implemented in MacPerl. See perl
port.
Execution of %s aborted due to compilation errors
(F) The final summary message when a Perl compilation fails.
Exiting eval via %s
(W exiting) You are exiting an eval by unconventional means, such
as a goto, or a loop control statement.
Exiting format via %s
(W exiting) You are exiting a format by unconventional means, such
as a goto, or a loop control statement.
Exiting pseudo-block via %s
(W exiting) You are exiting a rather special block construct (like
a sort block or subroutine) by unconventional means, such as a
goto, or a loop control statement. See "sort" in perlfunc.
Exiting subroutine via %s
(W exiting) You are exiting a subroutine by unconventional means,
such as a goto, or a loop control statement.
Exiting substitution via %s
(W exiting) You are exiting a substitution by unconventional means,
such as a return, a goto, or a loop control statement.
Explicit blessing to (assuming package main)
(W misc) You are blessing a reference to a zero length string.
This has the effect of blessing the reference into the package
main. This is usually not what you want. Consider providing a
default target package, e.g. bless($ref, $p || MyPackage);
%s: Expression syntax
(A) Youve accidentally run your script through csh instead of
Perl. Check the #! line, or manually feed your script into Perl
yourself.
%s failed--call queue aborted
(F) An untrapped exception was raised while executing a CHECK,
INIT, or END subroutine. Processing of the remainder of the queue
of such routines has been prematurely ended.
False [] range "%s" in regex; marked by " or "+>>" instead of with "" or ">>". See "open" in
perlfunc.
Filehandle %s opened only for output
(W io) You tried to read from a filehandle opened only for writing,
If you intended it to be a read/write filehandle, you needed to
open it with "+" or "+>>" instead of with "". Usually, this means that you supplied a "glob"
pattern that caused the external program to fail and exit with a
nonzero status. If the message indicates that the abnormal exit
resulted in a coredump, this may also mean that your csh (C shell)
is broken. If so, you should change all of the csh-related vari
ables in config.sh: If you have tcsh, make the variables refer to
it as if it were csh (e.g. "full_csh=/usr/bin/tcsh"); otherwise,
make them all empty (except that "d_csh" should be undef) so that
Perl will think csh is missing. In either case, after editing con
fig.sh, run "./Configure -S" and rebuild Perl.
Glob not terminated
(F) The lexer saw a left angle bracket in a place where it was
expecting a term, so its looking for the corresponding right angle
bracket, and not finding it. Chances are you left some needed
parentheses out earlier in the line, and you really meant a "less
than".
Got an error from DosAllocMem
(P) An error peculiar to OS/2. Most probably youre using an obso
lete version of Perl, and this should not happen anyway.
goto must have label
(F) Unlike with "next" or "last", youre not allowed to goto an
unspecified destination. See "goto" in perlfunc.
()-group starts with a count
(F) A ()-group started with a count. A count is supposed to follow
something: a template character or a ()-group.
See "pack" in perlfunc.
%s had compilation errors
(F) The final summary message when a "perl -c" fails.
Had to create %s unexpectedly
(S internal) A routine asked for a symbol from a symbol table that
ought to have existed already, but for some reason it didnt, and
had to be created on an emergency basis to prevent a core dump.
Hash %%s missing the % in argument %d of %s()
(D deprecated) Really old Perl let you omit the % on hash names in
some spots. This is now heavily deprecated.
%s has too many errors
(F) The parser has given up trying to parse the program after 10
errors. Further error messages would likely be uninformative.
Hexadecimal number > 0xffffffff non-portable
(W portable) The hexadecimal number you specified is larger than
2**32-1 (4294967295) and therefore non-portable between systems.
See perlport for more on portability concerns.
Identifier too long
(F) Perl limits identifiers (names for variables, functions, etc.)
to about 250 characters for simple names, and somewhat more for
compound names (like $A::B). Youve exceeded Perls limits.
Future versions of Perl are likely to eliminate these arbitrary
limitations.
Illegal binary digit %s
(F) You used a digit other than 0 or 1 in a binary number.
Illegal binary digit %s ignored
(W digit) You may have tried to use a digit other than 0 or 1 in a
binary number. Interpretation of the binary number stopped before
the offending digit.
Illegal character %s (carriage return)
(F) Perl normally treats carriage returns in the program text as it
would any other whitespace, which means you should never see this
error when Perl was built using standard options. For some reason,
your version of Perl appears to have been built without this sup
port. Talk to your Perl administrator.
Illegal character in prototype for %s : %s
(W syntax) An illegal character was found in a prototype declara
tion. Legal characters in prototypes are $, @, %, *, ;, [, ], &,
and \.
Illegal declaration of anonymous subroutine
(F) When using the "sub" keyword to construct an anonymous subrou
tine, you must always specify a block of code. See perlsub.
Illegal declaration of subroutine %s
(F) A subroutine was not declared correctly. See perlsub.
Illegal division by zero
(F) You tried to divide a number by 0. Either something was wrong
in your logic, or you need to put a conditional in to guard against
meaningless input.
Illegal hexadecimal digit %s ignored
(W digit) You may have tried to use a character other than 0 - 9 or
A - F, a - f in a hexadecimal number. Interpretation of the hex
adecimal number stopped before the illegal character.
Illegal modulus zero
(F) You tried to divide a number by 0 to get the remainder. Most
numbers dont take to this kindly.
Illegal number of bits in vec
(F) The number of bits in vec() (the third argument) must be a
power of two from 1 to 32 (or 64, if your platform supports that).
Illegal octal digit %s
(F) You used an 8 or 9 in an octal number.
Illegal octal digit %s ignored
(W digit) You may have tried to use an 8 or 9 in an octal number.
Interpretation of the octal number stopped before the 8 or 9.
Illegal switch in PERL5OPT: %s
(X) The PERL5OPT environment variable may only be used to set the
following switches: -[DIMUdmtw].
Ill-formed CRTL environ value "%s"
(W internal) A warning peculiar to VMS. Perl tried to read the
CRTLs internal environ array, and encountered an element without
the "=" delimiter used to separate keys from values. The element
is ignored.
Ill-formed message in prime_env_iter: |%s|
(W internal) A warning peculiar to VMS. Perl tried to read a logi
cal name or CLI symbol definition when preparing to iterate over
%ENV, and didnt see the expected delimiter between key and value,
so the line was ignored.
(in cleanup) %s
(W misc) This prefix usually indicates that a DESTROY() method
raised the indicated exception. Since destructors are usually
called by the system at arbitrary points during execution, and
often a vast number of times, the warning is issued only once for
any number of failures that would otherwise result in the same mes
sage being repeated.
Failure of user callbacks dispatched using the "G_KEEPERR" flag
could also result in this warning. See "G_KEEPERR" in perlcall.
In EBCDIC the v-string components cannot exceed 2147483647
(F) An error peculiar to EBCDIC. Internally, v-strings are stored
as Unicode code points, and encoded in EBCDIC as UTF-EBCDIC. The
UTF-EBCDIC encoding is limited to code points no larger than
2147483647 (0x7FFFFFFF).
Insecure dependency in %s
(F) You tried to do something that the tainting mechanism didnt
like. The tainting mechanism is turned on when youre running
setuid or setgid, or when you specify -T to turn it on explicitly.
The tainting mechanism labels all data thats derived directly or
indirectly from the user, who is considered to be unworthy of your
trust. If any such data is used in a "dangerous" operation, you
get this error. See perlsec for more information.
Insecure directory in %s
(F) You cant use system(), exec(), or a piped open in a setuid or
setgid script if $ENV{PATH} contains a directory that is writable
by the world. Also, the PATH must not contain any relative direc
tory. See perlsec.
Insecure $ENV{%s} while running %s
(F) You cant use system(), exec(), or a piped open in a setuid or
setgid script if any of $ENV{PATH}, $ENV{IFS}, $ENV{CDPATH},
$ENV{ENV}, $ENV{BASH_ENV} or $ENV{TERM} are derived from data sup
plied (or potentially supplied) by the user. The script must set
the path to a known value, using trustworthy data. See perlsec.
Integer overflow in %s number
(W overflow) The hexadecimal, octal or binary number you have spec
ified either as a literal or as an argument to hex() or oct() is
too big for your architecture, and has been converted to a floating
point number. On a 32-bit architecture the largest hexadecimal,
octal or binary number representable without overflow is
0xFFFFFFFF, 037777777777, or 0b11111111111111111111111111111111
respectively. Note that Perl transparently promotes all numbers to
a floating point representation internally--subject to loss of pre
cision errors in subsequent operations.
Internal disaster in regex; marked by or 2>> on command line
(F) An error peculiar to VMS. Perl handles its own command line
redirection, and found a 2> or a 2>> on the command line, but
cant find the name of the file to which to write data destined for
stderr.
No group ending character %c found in template
(F) A pack or unpack template has an opening ( or [ without its
matching counterpart. See "pack" in perlfunc.
No input file after < on command line
(F) An error peculiar to VMS. Perl handles its own command line
redirection, and found a < on the command line, but cant find
the name of the file from which to read data for stdin.
No #! line
(F) The setuid emulator requires that scripts have a well-formed #!
line even on machines that dont support the #! construct.
"no" not allowed in expression
(F) The "no" keyword is recognized and executed at compile time,
and returns no useful value. See perlmod.
No output file after > on command line
(F) An error peculiar to VMS. Perl handles its own command line
redirection, and found a lone > at the end of the command line,
so it doesnt know where you wanted to redirect stdout.
No output file after > or >> on command line
(F) An error peculiar to VMS. Perl handles its own command line
redirection, and found a > or a >> on the command line, but
cant find the name of the file to which to write data destined for
stdout.
No package name allowed for variable %s in "our"
(F) Fully qualified variable names are not allowed in "our" decla
rations, because that doesnt make much sense under existing
semantics. Such syntax is reserved for future extensions.
No Perl script found in input
(F) You called "perl -x", but no line was found in the file begin
ning with #! and containing the word "perl".
No setregid available
(F) Configure didnt find anything resembling the setregid() call
for your system.
No setreuid available
(F) Configure didnt find anything resembling the setreuid() call
for your system.
No %s specified for -%c
(F) The indicated command line switch needs a mandatory argument,
but you havent specified one.
No such class %s
(F) You provided a class qualifier in a "my" or "our" declaration,
but this class doesnt exist at this point in your program.
No such pipe open
(P) An error peculiar to VMS. The internal routine my_pclose()
tried to close a pipe which hadnt been opened. This should have
been caught earlier as an attempt to close an unopened filehandle.
No such pseudo-hash field "%s"
(F) You tried to access an array as a hash, but the field name used
is not defined. The hash at index 0 should map all valid field
names to array indices for that to work.
No such pseudo-hash field "%s" in variable %s of type %s
(F) You tried to access a field of a typed variable where the type
does not know about the field name. The field names are looked up
in the %FIELDS hash in the type package at compile time. The
%FIELDS hash is %usually set up with the fields pragma.
No such signal: SIG%s
(W signal) You specified a signal name as a subscript to %SIG that
was not recognized. Say "kill -l" in your shell to see the valid
signal names on your system.
Not a CODE reference
(F) Perl was trying to evaluate a reference to a code value (that
is, a subroutine), but found a reference to something else instead.
You can use the ref() function to find out what kind of ref it
really was. See also perlref.
Not a format reference
(F) Im not sure how you managed to generate a reference to an
anonymous format, but this indicates you did, and that it didnt
exist.
Not a GLOB reference
(F) Perl was trying to evaluate a reference to a "typeglob" (that
is, a symbol table entry that looks like *foo), but found a refer
ence to something else instead. You can use the ref() function to
find out what kind of ref it really was. See perlref.
Not a HASH reference
(F) Perl was trying to evaluate a reference to a hash value, but
found a reference to something else instead. You can use the ref()
function to find out what kind of ref it really was. See perlref.
Not an ARRAY reference
(F) Perl was trying to evaluate a reference to an array value, but
found a reference to something else instead. You can use the ref()
function to find out what kind of ref it really was. See perlref.
Not a perl script
(F) The setuid emulator requires that scripts have a well-formed #!
line even on machines that dont support the #! construct. The
line must mention perl.
Not a SCALAR reference
(F) Perl was trying to evaluate a reference to a scalar value, but
found a reference to something else instead. You can use the ref()
function to find out what kind of ref it really was. See perlref.
Not a subroutine reference
(F) Perl was trying to evaluate a reference to a code value (that
is, a subroutine), but found a reference to something else instead.
You can use the ref() function to find out what kind of ref it
really was. See also perlref.
Not a subroutine reference in overload table
(F) An attempt was made to specify an entry in an overloading table
that doesnt somehow point to a valid subroutine. See overload.
Not enough arguments for %s
(F) The function requires more arguments than you specified.
Not enough format arguments
(W syntax) A format specified more picture fields than the next
line supplied. See perlform.
%s: not found
(A) Youve accidentally run your script through the Bourne shell
instead of Perl. Check the #! line, or manually feed your script
into Perl yourself.
no UTC offset information; assuming local time is UTC
(S) A warning peculiar to VMS. Perl was unable to find the local
timezone offset, so its assuming that local system time is equiva
lent to UTC. If its not, define the logical name SYS$TIME
ZONE_DIFFERENTIAL to translate to the number of seconds which need
to be added to UTC to get local time.
Non-string passed as bitmask
(W misc) A number has been passed as a bitmask argument to
select(). Use the vec() function to construct the file descriptor
bitmasks for select. See "select" in perlfunc
Null filename used
(F) You cant require the null filename, especially because on many
machines that means the current directory! See "require" in perl
func.
NULL OP IN RUN
(P debugging) Some internal routine called run() with a null opcode
pointer.
Null picture in formline
(F) The first argument to formline must be a valid format picture
specification. It was found to be empty, which probably means you
supplied it an uninitialized value. See perlform.
Null realloc
(P) An attempt was made to realloc NULL.
NULL regexp argument
(P) The internal pattern matching routines blew it big time.
NULL regexp parameter
(P) The internal pattern matching routines are out of their gourd.
Number too long
(F) Perl limits the representation of decimal numbers in programs
to about 250 characters. Youve exceeded that length. Future ver
sions of Perl are likely to eliminate this arbitrary limitation.
In the meantime, try using scientific notation (e.g. "1e6" instead
of "1_000_000").
Octal number in vector unsupported
(F) Numbers with a leading 0 are not currently allowed in vectors.
The octal number interpretation of such numbers may be supported in
a future version.
Octal number > 037777777777 non-portable
(W portable) The octal number you specified is larger than 2**32-1
(4294967295) and therefore non-portable between systems. See perl
port for more on portability concerns.
See also perlport for writing portable code.
Odd number of arguments for overload::constant
(W overload) The call to overload::constant contained an odd number
of arguments. The arguments should come in pairs.
Odd number of elements in anonymous hash
(W misc) You specified an odd number of elements to initialize a
hash, which is odd, because hashes come in key/value pairs.
Odd number of elements in hash assignment
(W misc) You specified an odd number of elements to initialize a
hash, which is odd, because hashes come in key/value pairs.
Offset outside string
(F) You tried to do a read/write/send/recv operation with an offset
pointing outside the buffer. This is difficult to imagine. The
sole exception to this is that "sysread()"ing past the buffer will
extend the buffer and zero pad the new area.
%s() on unopened %s
(W unopened) An I/O operation was attempted on a filehandle that
was never initialized. You need to do an open(), a sysopen(), or a
socket() call, or call a constructor from the FileHandle package.
-%s on unopened filehandle %s
(W unopened) You tried to invoke a file test operator on a filehan
dle that isnt open. Check your control flow. See also "-X" in
perlfunc.
oops: oopsAV
(S internal) An internal warning that the grammar is screwed up.
oops: oopsHV
(S internal) An internal warning that the grammar is screwed up.
Operation "%s": no method found, %s
(F) An attempt was made to perform an overloaded operation for
which no handler was defined. While some handlers can be autogen
erated in terms of other handlers, there is no default handler for
any operation, unless "fallback" overloading key is specified to be
true. See overload.
Operator or semicolon missing before %s
(S ambiguous) You used a variable or subroutine call where the
parser was expecting an operator. The parser has assumed you
really meant to use an operator, but this is highly likely to be
incorrect. For example, if you say "*foo *foo" it will be inter
preted as if you said "*foo * foo".
"our" variable %s redeclared
(W misc) You seem to have already declared the same global once
before in the current lexical scope.
Out of memory!
(X) The malloc() function returned 0, indicating there was insuffi
cient remaining memory (or virtual memory) to satisfy the request.
Perl has no option but to exit immediately.
At least in Unix you may be able to get past this by increasing
your process datasize limits: in csh/tcsh use "limit" and "limit
datasize n" (where "n" is the number of kilobytes) to check the
current limits and change them, and in ksh/bash/zsh use "ulimit -a"
and "ulimit -d n", respectively.
Out of memory during %s extend
(X) An attempt was made to extend an array, a list, or a string
beyond the largest possible memory allocation.
Out of memory during "large" request for %s
(F) The malloc() function returned 0, indicating there was insuffi
cient remaining memory (or virtual memory) to satisfy the request.
However, the request was judged large enough (compile-time default
is 64K), so a possibility to shut down by trapping this error is
granted.
Out of memory during request for %s
(X|F) The malloc() function returned 0, indicating there was insuf
ficient remaining memory (or virtual memory) to satisfy the
request.
The request was judged to be small, so the possibility to trap it
depends on the way perl was compiled. By default it is not trap
pable. However, if compiled for this, Perl may use the contents of
$^M as an emergency pool after die()ing with this message. In this
case the error is trappable once, and the error message will
include the line and file where the failed request happened.
Out of memory during ridiculously large request
(F) You cant allocate more than 2^31+"small amount" bytes. This
error is most likely to be caused by a typo in the Perl program.
e.g., $arr[time] instead of $arr[$time].
Out of memory for yacc stack
(F) The yacc parser wanted to grow its stack so it could continue
parsing, but realloc() wouldnt give it more memory, virtual or
otherwise.
@ outside of string in unpack
(F) You had a template that specified an absolute position outside
the string being unpacked. See "pack" in perlfunc.
%s package attribute may clash with future reserved word: %s
(W reserved) A lowercase attribute name was used that had a pack
age-specific handler. That name might have a meaning to Perl
itself some day, even though it doesnt yet. Perhaps you should
use a mixed-case attribute name, instead. See attributes.
pack/unpack repeat count overflow
(F) You cant specify a repeat count so large that it overflows
your signed integers. See "pack" in perlfunc.
page overflow
(W io) A single call to write() produced more lines than can fit on
a page. See perlform.
panic: %s
(P) An internal error.
panic: ck_grep
(P) Failed an internal consistency check trying to compile a grep.
panic: ck_split
(P) Failed an internal consistency check trying to compile a split.
panic: corrupt saved stack index
(P) The savestack was requested to restore more localized values
than there are in the savestack.
panic: del_backref
(P) Failed an internal consistency check while trying to reset a
weak reference.
panic: Devel::DProf inconsistent subroutine return
(P) Devel::DProf called a subroutine that exited using goto(LABEL),
last(LABEL) or next(LABEL). Leaving that way a subroutine called
from an XSUB will lead very probably to a crash of the interpreter.
This is a bug that will hopefully one day get fixed.
panic: die %s
(P) We popped the context stack to an eval context, and then dis
covered it wasnt an eval context.
panic: do_subst
(P) The internal pp_subst() routine was called with invalid opera
tional data.
panic: do_trans_%s
(P) The internal do_trans routines were called with invalid opera
tional data.
panic: frexp
(P) The library function frexp() failed, making printf("%f") impos
sible.
panic: goto
(P) We popped the context stack to a context with the specified
label, and then discovered it wasnt a context we know how to do a
goto in.
panic: INTERPCASEMOD
(P) The lexer got into a bad state at a case modifier.
panic: INTERPCONCAT
(P) The lexer got into a bad state parsing a string with brackets.
panic: kid popen errno read
(F) forked child returned an incomprehensible message about its
errno.
panic: last
(P) We popped the context stack to a block context, and then dis
covered it wasnt a block context.
panic: leave_scope clearsv
(P) A writable lexical variable became read-only somehow within the
scope.
panic: leave_scope inconsistency
(P) The savestack probably got out of sync. At least, there was an
invalid enum on the top of it.
panic: magic_killbackrefs
(P) Failed an internal consistency check while trying to reset all
weak references to an object.
panic: malloc
(P) Something requested a negative number of bytes of malloc.
panic: mapstart
(P) The compiler is screwed up with respect to the map() function.
panic: memory wrap
(P) Something tried to allocate more memory than possible.
panic: null array
(P) One of the internal array routines was passed a null AV
pointer.
panic: pad_alloc
(P) The compiler got confused about which scratch pad it was allo
cating and freeing temporaries and lexicals from.
panic: pad_free curpad
(P) The compiler got confused about which scratch pad it was allo
cating and freeing temporaries and lexicals from.
panic: pad_free po
(P) An invalid scratch pad offset was detected internally.
panic: pad_reset curpad
(P) The compiler got confused about which scratch pad it was allo
cating and freeing temporaries and lexicals from.
panic: pad_sv po
(P) An invalid scratch pad offset was detected internally.
panic: pad_swipe curpad
(P) The compiler got confused about which scratch pad it was allo
cating and freeing temporaries and lexicals from.
panic: pad_swipe po
(P) An invalid scratch pad offset was detected internally.

(P) The foreach iterator got called in a non-loop context frame.
panic: pp_match%s
(P) The internal pp_match() routine was called with invalid opera
tional data.
panic: pp_split
(P) Something terrible went wrong in setting up for the split.
panic: realloc
(P) Something requested a negative number of bytes of realloc.
panic: restartop
(P) Some internal routine requested a goto (or something like it),
and didnt supply the destination.
panic: return
(P) We popped the context stack to a subroutine or eval context,
and then discovered it wasnt a subroutine or eval context.
panic: scan_num
(P) scan_num() got called on something that wasnt a number.
panic: sv_insert
(P) The sv_insert() routine was told to remove more string than
there was string.
panic: top_env
(P) The compiler attempted to do a goto, or something weird like
that.
panic: utf16_to_utf8: odd bytelen
(P) Something tried to call utf16_to_utf8 with an odd (as opposed
to even) byte length.
panic: yylex
(P) The lexer got into a bad state while processing a case modi
fier.
Parentheses missing around "%s" list
(W parenthesis) You said something like
my $foo, $bar = @_;
when you meant
my ($foo, $bar) = @_;
Remember that "my", "our", and "local" bind tighter than comma.
"-p" destination: %s
(F) An error occurred during the implicit output invoked by the
"-p" command-line switch. (This output goes to STDOUT unless
youve redirected it with select().)
(perhaps you forgot to load "%s"?)
(F) This is an educated guess made in conjunction with the message
"Cant locate object method \"%s\" via package \"%s\"". It often
means that a method requires a package that has not been loaded.
Perl %s required--this is only version %s, stopped
(F) The module in question uses features of a version of Perl more
recent than the currently running version. How long has it been
since you upgraded, anyway? See "require" in perlfunc.
PERL_SH_DIR too long
(F) An error peculiar to OS/2. PERL_SH_DIR is the directory to find
the "sh"-shell in. See "PERL_SH_DIR" in perlos2.
PERL_SIGNALS illegal: "%s"
See "PERL_SIGNALS" in perlrun for legal values.
perl: warning: Setting locale failed.
(S) The whole warning message will look something like:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LC_ALL = "En_US",
LANG = (unset)
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
Exactly what were the failed locale settings varies. In the above
the settings were that the LC_ALL was "En_US" and the LANG had no
value. This error means that Perl detected that you and/or your
operating system supplier and/or system administrator have set up
the so-called locale system but Perl could not use those settings.
This was not dead serious, fortunately: there is a "default locale"
called "C" that Perl can and will use, the script will be run.
Before you really fix the problem, however, you will get the same
error message each time you run Perl. How to really fix the prob
lem can be found in perllocale section LOCALE PROBLEMS.
Permission denied
(F) The setuid emulator in suidperl decided you were up to no good.
pid %x not a child
(W exec) A warning peculiar to VMS. Waitpid() was asked to wait
for a process which isnt a subprocess of the current process.
While this is fine from VMS perspective, its probably not what
you intended.
P must have an explicit size in unpack
(F) The unpack format P must have an explicit size, not "*".
-P not allowed for setuid/setgid script
(F) The script would have to be opened by the C preprocessor by
name, which provides a race condition that breaks security.
POSIX class [:%s:] unknown in regex; marked by 1, two => 2, }; # WRONG
%hash = [ qw/ an anon array / ]; # WRONG
%hash = ( one => 1, two => 2, ); # right
%hash = qw( one 1 two 2 ); # also fine
Reference is already weak
(W misc) You have attempted to weaken a reference that is already
weak. Doing so has no effect.
Reference miscount in sv_replace()
(W internal) The internal sv_replace() function was handed a new SV
with a reference count of other than 1.
Reference to nonexistent group in regex; marked by , and your operating system doesnt
support the seteuid() system call (or equivalent), or at least Con
figure didnt think so.
setpgrp cant take arguments
(F) Your system has the setpgrp() from BSD 4.2, which takes no
arguments, unlike POSIX setpgid(), which takes a process ID and
process group ID.
setrgid() not implemented
(F) You tried to assign to $(, and your operating system doesnt
support the setrgid() system call (or equivalent), or at least Con
figure didnt think so.
setruid() not implemented
(F) You tried to assign to $ should be quotes
(F) You wrote "require " when you should have written
"require file".
/%s/ should probably be written as "%s"
(W syntax) You have used a pattern where Perl expected to find a
string, as in the first argument to "join". Perl will treat the
true or false result of matching the pattern against $_ as the
string, which is probably not what you had in mind.
shutdown() on closed socket %s
(W closed) You tried to do a shutdown on a closed socket. Seems a
bit superfluous.
SIG%s handler "%s" not defined
(W signal) The signal handler named in %SIG doesnt, in fact,
exist. Perhaps you put it into the wrong package?
sort is now a reserved word
(F) An ancient error message that almost nobody ever runs into any
more. But before sort was a keyword, people sometimes used it as a
filehandle.
Sort subroutine didnt return a numeric value
(F) A sort comparison routine must return a number. You probably
blew it by not using "<=>" or "cmp", or by not using them cor
rectly. See "sort" in perlfunc.
Sort subroutine didnt return single value
(F) A sort comparison subroutine may not return a list value with
more or less than one element. See "sort" in perlfunc.
splice() offset past end of array
(W misc) You attempted to specify an offset that was past the end
of the array passed to splice(). Splicing will instead commence at
the end of the array, rather than past it. If this isnt what you
want, try explicitly pre-extending the array by assigning $#array =
$offset. See "splice" in perlfunc.
Split loop
(P) The split was looping infinitely. (Obviously, a split
shouldnt iterate more times than there are characters of input,
which is what happened.) See "split" in perlfunc.
Statement unlikely to be reached
(W exec) You did an exec() with some statement after it other than
a die(). This is almost always an error, because exec() never
returns unless there was a failure. You probably wanted to use
system() instead, which does return. To suppress this warning, put
the exec() in a block by itself.
stat() on unopened filehandle %s
(W unopened) You tried to use the stat() function on a filehandle
that was either never opened or has since been closed.
Stub found while resolving method "%s" overloading "%s"
(P) Overloading resolution over @ISA tree may be broken by importa
tion stubs. Stubs should never be implicitly created, but explicit
calls to "can" may break this.
Subroutine %s redefined
(W redefine) You redefined a subroutine. To suppress this warning,
say
{
no warnings redefine;
eval "sub name { ... }";
}
Substitution loop
(P) The substitution was looping infinitely. (Obviously, a substi
tution shouldnt iterate more times than there are characters of
input, which is what happened.) See the discussion of substitution
in "Quote and Quote-like Operators" in perlop.
Substitution pattern not terminated
(F) The lexer couldnt find the interior delimiter of an s/// or
s{}{} construct. Remember that bracketing delimiters count nesting
level. Missing the leading "$" from variable $s may cause this
error.
Substitution replacement not terminated
(F) The lexer couldnt find the final delimiter of an s/// or s{}{}
construct. Remember that bracketing delimiters count nesting
level. Missing the leading "$" from variable $s may cause this
error.
substr outside of string
(W substr),(F) You tried to reference a substr() that pointed out
side of a string. That is, the absolute value of the offset was
larger than the length of the string. See "substr" in perlfunc.
This warning is fatal if substr is used in an lvalue context (as
the left hand side of an assignment or as a subroutine argument for
example).
suidperl is no longer needed since %s
(F) Your Perl was compiled with -DSETUID_SCRIPTS_ARE_SECURE_NOW,
but a version of the setuid emulator somehow got run anyway.
Switch (?(condition)... contains too many branches in regex; marked by
create() failed
for some reason.
5.005 threads are deprecated
(D deprecated) The 5.005-style threads (activated by "use
Thread;") are deprecated and one should use the new ithreads
instead, see perl58delta for more details.
times not implemented
(F) Your version of the C library apparently doesnt do times(). I
suspect youre not running on Unix.
"-T" is on the #! line, it must also be used on the command line
(X) The #! line (or local equivalent) in a Perl script contains the
-T option, but Perl was not invoked with -T in its command line.
This is an error because, by the time Perl discovers a -T in a
script, its too late to properly taint everything from the envi
ronment. So Perl gives up.
If the Perl script is being executed as a command using the #!
mechanism (or its local equivalent), this error can usually be
fixed by editing the #! line so that the -T option is a part of
Perls first argument: e.g. change "perl -n -T" to "perl -T -n".
If the Perl script is being executed as "perl scriptname", then the
-T option must appear on the command line: "perl -T scriptname".
To%s: illegal mapping %s
(F) You tried to define a customized To-mapping for lc(), lcfirst,
uc(), or ucfirst() (or their string-inlined versions), but you
specified an illegal mapping. See "User-Defined Character Proper
ties" in perlunicode.
Too deeply nested ()-groups
(F) Your template contains ()-groups with a ridiculously deep nest
ing level.
Too few args to syscall
(F) There has to be at least one argument to syscall() to specify
the system call to call, silly dilly.
Too late for "-%s" option
(X) The #! line (or local equivalent) in a Perl script contains the
-M or -m option. This is an error because -M and -m options are
not intended for use inside scripts. Use the "use" pragma instead.
Too late to run %s block
(W void) A CHECK or INIT block is being defined during run time
proper, when the opportunity to run them has already passed.
Perhaps you are loading a file with "require" or "do" when you
should be using "use" instead. Or perhaps you should put the
"require" or "do" inside a BEGIN block.
Too many args to syscall
(F) Perl supports a maximum of only 14 args to syscall().
Too many arguments for %s
(F) The function requires fewer arguments than you specified.
Too many )s
(A) Youve accidentally run your script through csh instead of
Perl. Check the #! line, or manually feed your script into Perl
yourself.
Too many (s
(A) Youve accidentally run your script through csh instead of
Perl. Check the #! line, or manually feed your script into Perl
yourself.
Trailing \ in regex m/%s/
(F) The regular expression ends with an unbackslashed backslash.
Backslash it. See perlre.
Transliteration pattern not terminated
(F) The lexer couldnt find the interior delimiter of a tr/// or
tr[][] or y/// or y[][] construct. Missing the leading "$" from
variables $tr or $y may cause this error.
Transliteration replacement not terminated
(F) The lexer couldnt find the final delimiter of a tr///, tr[][],
y/// or y[][] construct.
%s trapped by operation mask
(F) You tried to use an operator from a Safe compartment in which
its disallowed. See Safe.
truncate not implemented
(F) Your machine doesnt implement a file truncation mechanism that
Configure knows about.
Type of arg %d to %s must be %s (not %s)
(F) This function requires the argument in that position to be of a
certain type. Arrays must be @NAME or "@{EXPR}". Hashes must be
%NAME or "%{EXPR}". No implicit dereferencing is allowed--use the
{EXPR} forms as an explicit dereference. See perlref.
umask not implemented
(F) Your machine doesnt implement the umask function and you tried
to use it to restrict permissions for yourself (EXPR & 0700).
Unable to create sub named "%s"
(F) You attempted to create or access a subroutine with an illegal
name.
Unbalanced context: %d more PUSHes than POPs
(W internal) The exit code detected an internal inconsistency in
how many execution contexts were entered and left.
Unbalanced saves: %d more saves than restores
(W internal) The exit code detected an internal inconsistency in
how many values were temporarily localized.
Unbalanced scopes: %d more ENTERs than LEAVEs
(W internal) The exit code detected an internal inconsistency in
how many blocks were entered and left.
Unbalanced tmps: %d more allocs than frees
(W internal) The exit code detected an internal inconsistency in
how many mortal scalars were allocated and freed.
Undefined format "%s" called
(F) The format indicated doesnt seem to exist. Perhaps its
really in another package? See perlform.
Undefined sort subroutine "%s" called
(F) The sort comparison routine specified doesnt seem to exist.
Perhaps its in a different package? See "sort" in perlfunc.
Undefined subroutine &%s called
(F) The subroutine indicated hasnt been defined, or if it was, it
has since been undefined.
Undefined subroutine called
(F) The anonymous subroutine youre trying to call hasnt been
defined, or if it was, it has since been undefined.
Undefined subroutine in sort
(F) The sort comparison routine specified is declared but doesnt
seem to have been defined yet. See "sort" in perlfunc.
Undefined top format "%s" called
(F) The format indicated doesnt seem to exist. Perhaps its
really in another package? See perlform.
Undefined value assigned to typeglob
(W misc) An undefined value was assigned to a typeglob, a la "*foo
= undef". This does nothing. Its possible that you really mean
"undef *foo".
%s: Undefined variable
(A) Youve accidentally run your script through csh instead of
Perl. Check the #! line, or manually feed your script into Perl
yourself.
unexec of %s into %s failed!
(F) The unexec() routine failed for some reason. See your local
FSF representative, who probably put it there in the first place.
Unicode character %s is illegal
(W utf8) Certain Unicode characters have been designated off-limits
by the Unicode standard and should not be generated. If you really
know what you are doing you can turn off this warning by "no warn
ings utf8;".
Unknown BYTEORDER
(F) There are no byte-swapping functions for a machine with this
byte order.
Unknown open() mode %s
(F) The second argument of 3-argument open() is not among the list
of valid modes: "", ">>", "+", "+>>", "-|", "|-",
"&".
Unknown PerlIO layer "%s"
(W layer) An attempt was made to push an unknown layer onto the
Perl I/O system. (Layers take care of transforming data between
external and internal representations.) Note that some layers,
such as "mmap", are not supported in all environments. If your
program didnt explicitly request the failing operation, it may be
the result of the value of the environment variable PERLIO.
Unknown process %x sent message to prime_env_iter: %s
(P) An error peculiar to VMS. Perl was reading values for %ENV
before iterating over it, and someone else stuck a message in the
stream of data Perl expected. Someones very confused, or perhaps
trying to subvert Perls population of %ENV for nefarious purposes.
Unknown "re" subpragma %s (known ones are: %s)
You tried to use an unknown subpragma of the "re" pragma.
Unknown switch condition (?(%.2s in regex; marked by operator
(F) The lexer saw a left angle bracket in a place where it was
expecting a term, so its looking for the corresponding right angle
bracket, and not finding it. Chances are you left some needed
parentheses out earlier in the line, and you really meant a "less
than".
untie attempted while %d inner references still exist
(W untie) A copy of the object returned from "tie" (or "tied") was
still valid when "untie" was called.
Usage: POSIX::%s(%s)
(F) You called a POSIX function with incorrect arguments. See
"FUNCTIONS" in POSIX for more information.
Usage: Win32::%s(%s)
(F) You called a Win32 function with incorrect arguments. See
Win32 for more information.
Useless (?-%s) - dont use /%s modifier in regex; marked by bar()" or
"$obj->bar()").
This bug will be rectified in future by using method lookup only
for methods "AUTOLOAD"s. However, there is a significant base of
existing code that may be using the old behavior. So, as an
interim step, Perl currently issues an optional warning when non-
methods use inherited "AUTOLOAD"s.
The simple rule is: Inheritance will not work when autoloading
non-methods. The simple fix for old code is: In any module that
used to depend on inheriting "AUTOLOAD" for non-methods from a base
class named "BaseClass", execute "*AUTOLOAD = \&Base
Class::AUTOLOAD" during startup.
In code that currently says "use AutoLoader; @ISA =
qw(AutoLoader);" you should remove AutoLoader from @ISA and change
"use AutoLoader;" to "use AutoLoader AUTOLOAD;".
Use of %s in printf format not supported
(F) You attempted to use a feature of printf that is accessible
from only C. This usually means theres a better way to do it in
Perl.
Use of $* is deprecated
(D deprecated) This variable magically turned on multi-line pattern
matching, both for you and for any luckless subroutine that you
happen to call. You should use the new "//m" and "//s" modifiers
now to do that without the dangerous action-at-a-distance effects
of $*.
Use of $# is deprecated
(D deprecated) This was an ill-advised attempt to emulate a poorly
defined awk feature. Use an explicit printf() or sprintf()
instead.
Use of %s is deprecated
(D deprecated) The construct indicated is no longer recommended for
use, generally because theres a better way to do it, and also
because the old way has bad side effects.
Use of -l on filehandle %s
(W io) A filehandle represents an opened file, and when you opened
the file it already went past any symlink you are presumably trying
to look for. The operation returned "undef". Use a filename
instead.
Use of "package" with no arguments is deprecated
(D deprecated) You used the "package" keyword without specifying a
package name. So no namespace is current at all. Using this can
cause many otherwise reasonable constructs to fail in baffling
ways. "use strict;" instead.
Use of reference "%s" as array index
(W misc) You tried to use a reference as an array index; this prob
ably isnt what you mean, because references in numerical context
tend to be huge numbers, and so usually indicates programmer error.
If you really do mean it, explicitly numify your reference, like
so: $array[0+$ref]. This warning is not given for overloaded
objects, either, because you can overload the numification and
stringification operators and then you assumedly know what you are
doing.
Use of reserved word "%s" is deprecated
(D deprecated) The indicated bareword is a reserved word. Future
versions of perl may use it as a keyword, so youre better off
either explicitly quoting the word in a manner appropriate for its
context of use, or using a different name altogether. The warning
can be suppressed for subroutine names by either adding a "&" pre
fix, or using a package qualifier, e.g. "&our()", or "Foo::our()".
Use of tainted arguments in %s is deprecated
(W taint, deprecated) You have supplied "system()" or "exec()" with
multiple arguments and at least one of them is tainted. This used
to be allowed but will become a fatal error in a future version of
perl. Untaint your arguments. See perlsec.
Use of uninitialized value%s
(W uninitialized) An undefined value was used as if it were already
defined. It was interpreted as a "" or a 0, but maybe it was a
mistake. To suppress this warning assign a defined value to your
variables.
To help you figure out what was undefined, perl tells you what
operation you used the undefined value in. Note, however, that
perl optimizes your program and the operation displayed in the
warning may not necessarily appear literally in your program. For
example, "that $foo" is usually optimized into ""that " . $foo",
and the warning will refer to the "concatenation (.)" operator,
even though there is no "." in your program.
Using a hash as a reference is deprecated
(D deprecated) You tried to use a hash as a reference, as in
"%foo->{"bar"}" or "%$ref->{"hello"}". Versions of perl <= 5.6.1
used to allow this syntax, but shouldnt have. It is now depre
cated, and will be removed in a future version.
Using an array as a reference is deprecated
(D deprecated) You tried to use an array as a reference, as in
"@foo->[23]" or "@$ref->[99]". Versions of perl <= 5.6.1 used to
allow this syntax, but shouldnt have. It is now deprecated, and
will be removed in a future version.
UTF-16 surrogate %s
(W utf8) You tried to generate half of an UTF-16 surrogate by
requesting a Unicode character between the code points 0xD800 and
0xDFFF (inclusive). That range is reserved exclusively for the use
of UTF-16 encoding (by having two 16-bit UCS-2 characters); but
Perl encodes its characters in UTF-8, so what you got is a very
illegal character. If you really know what you are doing you can
turn off this warning by "no warnings utf8;".
Value of %s can be "0"; test with defined()
(W misc) In a conditional expression, you used ,
(glob), "each()", or "readdir()" as a boolean value. Each of these
constructs can return a value of "0"; that would make the condi
tional expression false, which is probably not what you intended.
When using these constructs in conditional expressions, test their
values with the "defined" operator.
Value of CLI symbol "%s" too long
(W misc) A warning peculiar to VMS. Perl tried to read the value
of an %ENV element from a CLI symbol table, and found a resultant
string longer than 1024 characters. The return value has been
truncated to 1024 characters.
Variable "%s" is not imported%s
(F) While "use strict" in effect, you referred to a global variable
that you apparently thought was imported from another module,
because something else of the same name (usually a subroutine) is
exported by that module. It usually means you put the wrong funny
character on the front of your variable.
Variable length lookbehind not implemented in regex; marked by 255) when it wasnt expecting
one. This warning is by default on for I/O (like print). The eas
iest way to quiet this warning is simply to add the ":utf8" layer
to the output, e.g. "binmode STDOUT, :utf8". Another way to turn
off the warning is to add "no warnings utf8;" but that is often
closer to cheating. In general, you are supposed to explicitly
mark the filehandle with an encoding, see open and "binmode" in
perlfunc.
Within []-length %c not allowed
(F) The count in the (un)pack template may be replaced by "[TEM
PLATE]" only if "TEMPLATE" always matches the same amount of packed
bytes that can be determined from the template alone. This is not
possible if it contains an of the codes @, /, U, u, w or a
*-length. Redesign the template.
write() on closed filehandle %s
(W closed) The filehandle youre writing to got itself closed some
time before now. Check your control flow.
%s "\x%s" does not map to Unicode
When reading in different encodings Perl tries to map everything
into Unicode characters. The bytes you read in are not legal in
this encoding, for example
utf8 "\xE4" does not map to Unicode
if you try to read in the a-diaereses Latin-1 as UTF-8.
X outside of string
(F) You had a (un)pack template that specified a relative position
before the beginning of the string being (un)packed. See "pack" in
perlfunc.
x outside of string in unpack
(F) You had a pack template that specified a relative position
after the end of the string being unpacked. See "pack" in perl
func.
YOU HAVENT DISABLED SET-ID SCRIPTS IN THE KERNEL YET!
(F) And you probably never will, because you probably dont have
the sources to your kernel, and your vendor probably doesnt give a
rip about what you want. Your best bet is to put a setuid C wrap
per around your script.
You need to quote "%s"
(W syntax) You assigned a bareword as a signal handler name.
Unfortunately, you already have a subroutine of that name declared,
which means that Perl 5 will try to call the subroutine when the
assignment is executed, which is probably not what you want. (If
it IS what you want, put an & in front.)
Your random numbers are not that random
(F) When trying to initialise the random seed for hashes, Perl
could not get any randomness out of your system. This usually
indicates Something Very Wrong.
perl v5.8.8 2008-04-25 PERLDIAG(1)
